REGISTER-CONTROLLER.

Specification of Letters Patent.

Patented Oct. 24, 1916.

To all whom it may concern:

Be it known that I,'ALFRED H. DYsoN, a citizen of the United States, residing at Montclair, in the county of Essex and State of New Jersey, have invented certain new.

and useful Improvements in Register-Controllers, of which the following is a full, clear, concise, and exact description.

This invention relates to register-com trollers, and particularly to register-controllers for use in a semi-automatic telephone exchange system in which the number of the calling subscribers line is temporarily registered at the central ofiice and t0 directively control switching apparatus in accordance with the registered number.

The object of the invention is the provision of an improved number register-com troller for use in a semi-automatic telephone system.

In practice, as many of these register'controllers will be employed per group of subscribers as there are digits in any calling subscribers number, usually four, representing digits of said number. For the manner in which these register-controllers are to be used in connection with a telephone exchange system, reference may be had to applicants co-pending application, Serial No. 49,524, filed September 8, 1915.

In the drawings, Figure 1 is a plan view of the register-controller; Fig. 2 is a perspective elevation; and Fig. 3 is a sectional elevation on the line 3-3 of Fig. 1, showing the arm driving mechanism.

The device comprises two sector-shaped plates 10 and 11 spaced apart in any convenient manner, the upper plate 10 having mounted thereon five magnets 12 to 16 inclusive, the lower plate 11 havin the magnets 17 to 21 inclusive mounted thereon, the magnets 12 to 21 inclusive representing the ten digits. Each of the magnets has pivotally mounted in operative relation to the core thereof an L-shaped armature 22, the depending portion of which operates a pair of contacts 23 and 24, the horizontal portion operating to depress a vertically movable member 25 having bearings in the upper and lower plates 10 and 11 respectively, and being held normally in position with respect to the plates 10 and 11 by a spring 26, one end of which bears on the plate 10 or 11, as the case may be, and the other end abutting against a pin 27 passing through the vertically movable member 25. Intermediate to the ends of the vertically movable member 25 is a projecting portion 28 for a purpose to be hereinafter described. A stationary shaft 29 is mounted one end in the plate 10 and the other in the plate 11. Fastened to said shaft 29, in any convenient manner, as

by a screw 30, is a hollow member 31, to which is fastened the outer end of a driving spring 32, the inner end of said s ring being fastened to the depending hu 33 of a ratchet wheel 34. F astened to the ratchet wheel 34 is an arm 35. The ratchet wheel 34 and arm 35 are held in operative relation to the member 31 by a collar 36 fastened to the shaft 29 by the screw 37. The arm 35 carries at its outer end a pivotally mounted rejection 38 which, when the arm 35 rotates in the direction of the arrow as shown in Fig. 1, is adapted to strike against the rejeetion 28 on the vertically movable r0 25 of any of the magnets 12 to 21 inclusive thereby stopping the arm 35 in such position.

In the normal position of the arm 35, as shown in Fig. 1, the contacts 39 are closed, remaining in this position until oneof the magnets 12 to 21 inclusive of each of the thousands, hundreds, tens and units recorders are energized, the magnets energized representing the digits of the eallin subscribers number, at which time a eireult will be closed through the contacts 23, 24 of the,

thousands, hundreds, tens and units recorders in series from battery, release magnet 40, conductor 59, contacts 39, conductor 60, contacts 23, 24 to ground, energizing the release magnet 40 which attracts its armature 41, moving the pawl 42 out of engagement with the ratchet 34 and also closing contacts 43. This energizing circuit for release magnet 40 is broken at the contacts 39 as soon as the arm 35 moves away from its normal position. As, however, the release magnet 40 must be fully energized before the release of the arm 35 takes place, a supplementary energizing circuit is established for said release magnet, this circuit being from battery, through'the winding of the release magnet, the contacts 43 (closed by the attraction of the armature 41), the contacts 44 on the arm to ground. This supplementary energizing circuit for the release magnet will be maintained until the projection 38 on the arm 35 comes into engagement with the projection 28 on the .ver-

tically movable rod 25. Immediately the projection 38 comes into engagement with the projection 28, the arm 35 is stopped and contact 44 broken, destroying the energizing circuit for the release magnet and allowing the pawl 42 to move into engagement with the ratchet 34.

\Vhen the arm 35 moved from its normal position, breaking the circuit for the offnormal contacts 39, it closed a circuit at the contacts 45 for the sequence switches of the thousands, hundreds, tens or units registers described and shown in the co-pending application above referred to. On the arm 35 being stopped by the engagement of the projection 38 with the projection 28 of a vertically movable rod 25, contact is made at springs 46, completing an energizing circuit for certain mechanism (not shown). The arm is now returned to normal position by the stepping magnet 47, which is intermittently energized and de'energized in any convenient manner as by the operation of a key 61. Depression of key 61 closes a circuit from battery, stepping magnet 47, conductor 62, key 61 to ground, energizing said stepping magnet, which attracts its arma ture 48, the pawl 49, pivotally mounted thereon, moving into engagement with the ratchet 34, stepping the arm 35 back toward its normal position the distance of one toothon the ratchet 34, the arm being prevented from moving outward again by the pawl 42 on the release magnet 40. As the stepping magnet 47 energizes, the outer end of the backward extension 50 of the armature 48 moves upward, as viewed in Fig. 1, carrying therewith the pivoted member 51 having a notch and cam on its extreme end. The pivoted member 51 is held to the right, as viewed in Fig. 1, by the spring 52, with the notch at the extreme end thereof in engagement with a spring lever 53, which is placed in operative relation to but insulated from one of the spring contact members 54. The energizing circuit, traced above for the stepping magnet 47, went to ground at the key 61. To insure that the stepping magnet remains energized until its armature is fully attracted, irrespective of what happens at key 61, a supplementary energizing circuit is provided as follows: The stepping magnet being energized attracts its armature, and a projection 55 on the pivoted member 51 closes contact springs 56, completing a circuit from battery, stepping magnet, conductors 62, 63, contact springs 54 and 56, to ground.

The circuit to the apparatus to be controlled by this device may be connected be tween springs 54 and 56 in place of the connection between these springs as shown in the drawing. This control circuit is opened and closed by the operation of the armature of the magnet. This is clearly shown in the cam face and onto the inner portion, breakapplicants copending application to which reference has been heretofore made. This last traced circuit remains closed until the armature 48 approaches its extreme limit of travel, at which time the member 51 will have forced the spring member 53 outwardly and into engagement with a limiting stop 57. Further movement on the part of the armature 48 causes the pivoted member 51 to move outwardly, the cam surface on the extreme end thereof riding up on the spring member 53 until, when the limit of movement of the armature 48 is reached, spring member 53 slips off the outer portion of the ing the contact existing at contact springs 54. The breaking of the contact between the springs 54 in turn breaks and keeps broken the energizing circuit for stepping magnet 47 and for the circuit between springs 54 and 56 until the armature 48 thereof has been fully retracted.

As the armature 48 approaches its retracted position the spring member 53 rides up on the lower cam surface, on the extreme end of pivoted member 51, and spring member 53 moves into engagement with a limiting stop 58. When the limit of return movementof the armature 48 is reached, the spring member 53 will have ridden over the lower face of the cam and into the slot, the mechanism resuming its normal position. For each step of the arm 35 backward, it is obvious that the control circuit to the connected apparatus is made and broken, thus controlling the operation of the said apparatus in any well-known manner.

The register-controller has been shown with two groups of magnets of five each to represent the ten digits, the magnets being arranged five on the top plate 10 and five on the bottom plate 11. This arrangement has only been adopted for the purpose of saving space, and it will, of course, be apparent that it would be erfectly feasible to 11 arrange the magnets all on the same plate or to. even group them differently on the same or on any number of plates.
